You should listen better. Yes, the position of earth to the sun initiateded those climate changes, but large part of the temperature rise/fall in those periods actually comes from more/less co2 in the atmosphere

So you ignored the presentation by a science based source, only to then pretended to be "the expert" instead. Ok then 😂😂😂 Your classic tired old contrarian talking points, which have been well and truly dealt with over and over and over, keep getting mischievously recycled it seems. Why are you or anyone still trying to employ them?

@@BrentonSmythesfieldsaye . I forget how many people have debunked the control knob myth so far , all of them are scientists in geology and physics fields so go away little troll.

@@anomamos9095 You mean you have heard all the mischief from fossil fuel industry affiliated political ideologues that have not done any actual scientific rersearch or provided any evidence supporting their claims and narratives. Just spouted the same question and talking points like you have. So all you have heard is FUD and you have fallen for it. Ok then that is your poroblem. Also if you are going to employ the fallacy of an "argument from authority", as in you have heard all this "debunking" from "scientists in geology and physics fields", then it should be easy for you to cite all their peer reviewed research papers, published in respected journals, so your claim can be confirmed. Then you be comfortable that you have not commited the argument from authority fallacy. Good luck, you will need it. Richard B Allen, could provide a tsunami of peer reviewed research papers from respected journals, that lay out the evidence for the content he is presenting.

@@anomamos9095 Nothing changed! If you insisting on repeating mischievous irrelevant narratives over and over and over, it isn't going to make them true. When your supposed "scientists in geology and physics fields" have published research that has been published in respected journals and undergone peeer review, to the point that it successfully superceded the huge existing body of research and evidence regarding AGW, then we would all give a sigh of relief. But they haven't done that to date. Just crickets. All the contrarian perspective ever delivers is constant whinging in blog articles, media hit pieces, social media commentary all driven by political and ideological objections. No scientific research and evidence in support to be seen at all. All we hear is a perpetual contrarian soap opera. Looks like you have uncritically bought into that. Meanwhile reality continues to proceed, LOL.

@@anomamos9095 Total nonsense!

I agree
